Abstract:
Objective. To compare the efficacy of corticotropin (ACTH) (150 U/m2/day) and prednisone (2 mg/kg/day), given for 2 weeks, in suppressing clinical spasms and hypsarrhythmic electroencephalogram (EEG) in infantile spasms (IS). ACTH and prednisone are standard treatments for IS. ACTH at high doses causes severe dose- and duration-dependent side effects, but may be superior to prednisone, based on retrospective or uncontrolled studies. Blinded prospective studies have shown equal efficacy of prednisone and low-dose ACTH, and low versus high-dose ACTH. Design. A prospective, randomized, single-bli

Abstract:
West syndrome is a severe form of epilepsy with onset in infancy and early childhood. The characteristic triad described includes infantile spasms (IS), an abnormal electroencephalogram (EEG) pattern referred to as hypsarrhythmia, and developmental regression. It comprises 2% of childhood epilepsies. Etiologically, West syndrome can be classified into symptomatic with known etiology and cryptogenic with unknown etiology. Hypsarrhythmia is defined as chaotic, asynchronous, disorganized slow background activity with high-voltage spike activity. Burst-suppression pattern is a rarely described pat

Abstract:
Hypsarrhythmia is an electroencephalographic pattern specific to some epileptic syndromes that affect children under one year of age. The identification of this pattern, in some cases, causes disagreements between experts, which is worrisome since an inaccurate diagnosis can bring complications to the infant. Despite the difficulties in visually identifying hypsarrhythmia, options of computerized assistance are scarce. Aiming to collaborate with the recognition of this electropathological pattern, we propose in this paper a mathematical index that can help electroencephalography experts to ide

Background: West Syndrome (WS) consists of epileptic spasms, hypsarrhythmia on EEG and psychomotor delay or regression in children.
 Objective: To observe the clinical and laboratory profiles of children with west syndrome.
 Materials & Methods: This was a cross sectional study and done from July 2017 to June 2018 in Pediatric Neurology OPD, NINS among total 50 cases of WS (age of > 2 month to 2 years). WS was diagnosed by direct observation or video recording of spasm, along with history of developmental delay or regression and EEG change. Collected data regarding demography,

Abstract:
Spasms are defined as epileptic seizures characterized by brief axial contraction, in flexion, extension or mixed, symmetric or asymmetric, lasting from a fraction of a second to 1‐2s, and are associated with a slow‐wave transient or sharp and slow‐wave complex, followed or not by voltage attenuation. Epileptic spasms usually appear in clusters and are age‐dependent. This type of epileptic spasms associated with the particular EEG pattern, hypsarrhythmia, constitutes the basis for the diagnosis of West syndrome. The question is, how to nosologically define those patients who clearly present ep

Le syndrome de West (SW), communément appelé spasmes infantiles (SI), est un trouble épileptique généralement caractérisé par la triade de spasmes infantiles, un modèle d'électroencéphalogramme (EEG) pathognomonique appelé hypsarythmie, et la régression du développement. Alors que des études précédentes ont été en mesure d'obtenir une réponse relativement adéquate par rapport au contrôle des spasmes et la résolution d’hypsarythmie, elles n’ont pas réussi à fournir des options thérapeutiques décisives à l’égard des séquelles neurodéveloppementales souvent associées aux SI.

Abstract:
Electroencephalography (EEG) is an important part of the evaluation of many disorders in infants and children, including seizures and spells. This chapter identifies abnormal epileptiform patterns seen in infants and children and correlates these patterns to specific seizure types and electroclinical syndromes. Generalized discharge (associated with genetic generalized epilepsies as well as epileptic encephalopathies), focal discharge (associated with benign focal epilepsies as well as lesional epilepsies), and hypsarrhythmia are discussed. Additionally, abnormal, but non-epileptiform patterns

Context: We present a patient diagnosed with Tuberous Sclerosis (TS) who developed West Syndrome (WS) early on. Early diagnosis of TS is important for genetic counseling and WS requires early intervention to avoid neurodevelopmental deficits.

At 2 months old, she presented epileptic seizures of flexion spasms, which progressed in 1 week to neuropsychomotor development (NP) regression and hypsarrhythmia.
